Abstract

The invention relates to a temperature-controllable health-care microcapsule and a preparation method thereof. The preparation method includes the preparation steps of prepolymer preparing, compound core emulsion preparing, film formation by polymerization reaction, washing and drying. The temperature-controllable health-care microcapsule consists of a compound core and a wall material composed of high-molecular polymers, wherein the compound core is formed by blending adsorption of health-care functional powder and temperature-dependent phase change materials, the weight ratio of the composite core to the wall material is 0.3-3 to 1, average grain size of the health-care functional powder is not less than 1.2 micrometers, and average grain size of the microcapsule is not less than 3 micrometers. The temperature-controllable health-care microcapsule has the advantages that owing to the temperature control function of the microcapsule, release rate of trace elements of the functional powder in winter can be increased, human body subcutaneous microcirculation is reinforced, and human bodies' absorption of health-care active ingredients is improved; comfortable temperature between a clothing product and the skin of human bodies can be kept; the problem of dispersibility of the functional powder in blended spinning production can be solved.

Description

technical field [0001] The invention belongs to the technical field of microcapsule preparation, and relates to a temperature-controlled health-care microcapsule suitable for the textile field and a preparation method thereof. Background technique [0002] Microcapsule technology is a new type of technology that uses film-forming materials to coat tiny active particles into particles with a core-wall-shell structure. Microencapsulation of tiny active materials can effectively reduce the reaction of active materials to surrounding systems, including solid, liquid, gas and light, and effectively control their flow, release or expansion to the external environment. At present, microcapsule technology has been widely used in food, medicine, textile and engineering materials and other fields. [0003] Chinese patent application number 200610017695 discloses a textile nano-finishing agent with persistent antibacterial and aromatic effects and its manufacturing process. It uses a ...
